Pulling power decreases sharply per each millimeter of spacing. Remember that even a very thin break (e.g., dirt, varnish, dust) significantly weakens the grip. Magnets operate optimally during direct contact; gap drastically cuts the force. Observe how flashily the load capacity fall, when the magnet does not touch tightly to the metal substrate. When calculating the assembly, avoid redundant distances.

The table below defines the theoretical shear load required to cause the shifting of the magnet downwards along a vertical steel wall (considering typical friction coefficient). The holding force is a function of the air gap between the magnet and the metal.

Table 3: Vertical assembly (sliding) - vertical pull
MPL 20x3x2 / N38

Surface type	Friction coefficient / % Mocy	Max load (kg/lbs/g/N)
Raw steel	µ = 0.3 30% Nominalnej Siły	0.70 kg / 1.54 pounds 699.0 g / 6.9 N
Painted steel (standard)	µ = 0.2 20% Nominalnej Siły	0.47 kg / 1.03 pounds 466.0 g / 4.6 N
Oily/slippery steel	µ = 0.1 10% Nominalnej Siły	0.23 kg / 0.51 pounds 233.0 g / 2.3 N
Magnet with anti-slip rubber	µ = 0.5 50% Nominalnej Siły	1.17 kg / 2.57 pounds 1165.0 g / 11.4 N

When mounting a magnet on a vertical wall (e.g., a car body), it will only hold just approx. 20%-30% of nominal attraction strength. Gravity and a weak degree of grip mean that products move down faster than they detach. Planning a wall mount? Consider that the sliding force is much weaker than the perpendicular breakaway force. On a slippery surface, the holder will slip down under a noticeably lighter cargo. Utilizing a rubberized pad can significantly raise the stability.

Table 4: Steel thickness (saturation) - sheet metal selection
MPL 20x3x2 / N38

Steel thickness (mm)	% power	Real pull force (kg/lbs/g/N)
0.5 mm	10%	0.23 kg / 0.51 pounds 233.0 g / 2.3 N
1 mm	25%	0.58 kg / 1.28 pounds 582.5 g / 5.7 N
2 mm	50%	1.17 kg / 2.57 pounds 1165.0 g / 11.4 N
3 mm	75%	1.75 kg / 3.85 pounds 1747.5 g / 17.1 N
5 mm	100%	2.33 kg / 5.14 pounds 2330.0 g / 22.9 N
10 mm	100%	2.33 kg / 5.14 pounds 2330.0 g / 22.9 N
11 mm	100%	2.33 kg / 5.14 pounds 2330.0 g / 22.9 N
12 mm	100%	2.33 kg / 5.14 pounds 2330.0 g / 22.9 N

A too thin steel cannot focus the entire magnetic field, which wastes potential of the holder. If you install a neodymium to a thin surface, the magnetism will pass right through and the holding will be smaller. To squeeze the maximum of this magnet's power, you need a suitably thick piece of steel. The saturation phenomenon means that on thin elements (e.g., car bodies), the product holds weaker. We recommend selecting the steel cross-section according to the table below.

Table 5: Thermal stability (stability) - resistance threshold
MPL 20x3x2 / N38

Ambient temp. (°C)	Power loss	Remaining pull (kg/lbs/g/N)	Status

40 °C	-2.2%	2.28 kg / 5.02 pounds 2278.7 g / 22.4 N	OK
60 °C	-4.4%	2.23 kg / 4.91 pounds 2227.5 g / 21.9 N
80 °C	-6.6%	2.18 kg / 4.80 pounds 2176.2 g / 21.3 N
100 °C	-28.8%	1.66 kg / 3.66 pounds 1659.0 g / 16.3 N

Classic neodymiums irreversibly lose power past the thermal threshold. Protect against heat – high temperature can irreversibly destroy this magnet. With increasing heat, the neodymium's force briefly drops. Refrain from using this product close to ovens higher than its safe range. Exceeding the critical threshold will lead to permanent loss of magnetic properties.

*Engineering note: Thermal stability depends not only on the material grade, but also on the magnet's shape. Flat magnets (low permeance coefficient) are more susceptible to demagnetization at lower temperatures than taller cylinders. Warning indicator in the table points to permanent field degradation for this particular item.

Two magnets attract each other from a significantly greater distance than a magnet and sheet setup. The setup of two magnets produces a massive flux and a wider radius of action. Designing a solid fastener? Apply two magnets instead of a neodymium and a striker plate. Be careful that when connecting a pair of magnets, the pinch force is massive. The levitation is marginally weaker than the connection force, but still impressive.
*Field value for N-N configuration is approximately ~0 Gs in the exact middle between the magnets (resulting from vector opposition).
Important: Estimates apply to friction force of a pair of identical magnets (friction coefficient ~0.15 for Ni-Ni plating).

Powerful magnet radiation is a serious hazard to electronics as well as medical implants. These NdFeB products produce a flux that destroys function of sensitive medical devices. Notice: the invisible magnetic field passes through tissues and plastic. Increased vigilance must be exercised by people with hearing aids and insulin pumps. Also at risk are: mechanical watches, remotes, speakers, and displays. Do not place the magnet near cards, HDD media, or sensitive navigation tools.

Table 8: Collisions (kinetic energy) - collision effects
MPL 20x3x2 / N38

Start from (mm)	Speed (km/h)	Energy (J)

Magnetic elements are prone to chipping – a collision with steel causes immediate chipping. Control the attraction moment – a magnet released freely speeds with massive force. Striking energy can destroy the magnet or dangerous crushing to fingers. Hold the magnet firmly during mounting so it doesn't hit violently against the metal. A collision at high speed ends with a crack of the magnet. Use safety goggles when working with large magnets.

Warning: Standard nickel requires drying after every contact with moisture; lack of maintenance will lead to rust spots.

In water, the magnet feels stronger thanks to Archimedes' principle. However, remember the water resistance when pulling the rope quickly.

1. Sliding resistance

*Caution: On a vertical surface, the magnet holds merely approx. 20-30% of its max power.

2. Efficiency vs thickness

*Thin metal sheet (e.g. 0.5mm PC case) severely weakens the holding force.

3. Thermal stability

*For N38 material, the max working temp is 80°C.

4. Demagnetization curve and operating point (B-H)

chart generated for the permeance coefficient P_c (Permeance Coefficient) = 0.32

The chart above illustrates the magnetic characteristics of the material within the second quadrant of the hysteresis loop. The solid red line represents the demagnetization curve (material potential), while the dashed blue line is the load line based on the magnet's geometry. The P_c (Permeance Coefficient), also known as the load line slope, is a dimensionless value that describes the relationship between the magnet's shape and its magnetic stability. The intersection of these two lines (the black dot) is the operating point — it determines the actual magnetic flux density generated by the magnet in this specific configuration. A higher P_c value means the magnet is more 'slender' (tall relative to its area), resulting in a higher operating point and better resistance to irreversible demagnetization caused by external fields or temperature. A value of 0.42 is relatively low (typical for flat magnets), meaning the operating point is closer to the 'knee' of the curve — caution is advised when operating at temperatures near the maximum limit to avoid strength loss.

This product is a very powerful plate magnet made of NdFeB material, which, with dimensions of 20x3x2 mm and a weight of 0.9 g, guarantees premium class connection. As a magnetic bar with high power (approx. 2.33 kg), this product is available immediately from our warehouse in Poland. Additionally, its Ni-Cu-Ni coating protects it against corrosion in standard operating conditions, giving it an aesthetic appearance.

Separating block magnets requires a technique based on sliding (moving one relative to the other), rather than forceful pulling apart. To separate the MPL 20x3x2 / N38 model, firmly slide one magnet over the edge of the other until the attraction force decreases. We recommend extreme caution, because after separation, the magnets may want to violently snap back together, which threatens pinching the skin. Using a screwdriver risks destroying the coating and permanently cracking the magnet.

Plate magnets MPL 20x3x2 / N38 are the foundation for many industrial devices, such as magnetic separators and linear motors. They work great as invisible mounts under tiles, wood, or glass. Customers often choose this model for hanging tools on strips and for advanced DIY and modeling projects, where precision and power count.

Cyanoacrylate glues (super glue type) are good only for small magnets; for larger plates, we recommend resins. Double-sided tape cushions vibrations, which is an advantage when mounting in moving elements. Remember to roughen and wash the magnet surface before gluing, which significantly increases the adhesion of the glue to the nickel coating.

Standardly, the MPL 20x3x2 / N38 model is magnetized axially (dimension 2 mm), which means that the N and S poles are located on its largest, flat surfaces. In practice, this means that this magnet has the greatest attraction force on its main planes (20x3 mm), which is ideal for flat mounting. This is the most popular configuration for block magnets used in separators and holders.

The presented product is a neodymium magnet with precisely defined parameters: 20 mm (length), 3 mm (width), and 2 mm (thickness). It is a magnetic block with dimensions 20x3x2 mm and a self-weight of 0.9 g, ready to work at temperatures up to 80°C. The product meets the standards for N38 grade magnets.

Advantages and disadvantages of rare earth magnets.

Advantages

Apart from their strong magnetic energy, neodymium magnets have these key benefits:

They virtually do not lose power, because even after ten years the decline in efficiency is only ~1% (according to literature),
Neodymium magnets are distinguished by highly resistant to loss of magnetic properties caused by external interference,
By covering with a reflective layer of gold, the element has an modern look,
Magnetic induction on the top side of the magnet is very high,
Due to their durability and thermal resistance, neodymium magnets can operate (depending on the form) even at high temperatures reaching 230°C or more...
Thanks to flexibility in designing and the capacity to customize to client solutions,
Wide application in high-tech industry – they are utilized in HDD drives, electromotive mechanisms, medical devices, also complex engineering applications.
Thanks to their power density, small magnets offer high operating force, with minimal size,

Disadvantages

Disadvantages of neodymium magnets:

To avoid cracks upon strong impacts, we recommend using special steel housings. Such a solution secures the magnet and simultaneously increases its durability.
When exposed to high temperature, neodymium magnets suffer a drop in strength. Often, when the temperature exceeds 80°C, their strength decreases (depending on the size, as well as shape of the magnet). For those who need magnets for extreme conditions, we offer [AH] versions withstanding up to 230°C
When exposed to humidity, magnets start to rust. For applications outside, it is recommended to use protective magnets, such as those in rubber or plastics, which prevent oxidation as well as corrosion.
Due to limitations in creating threads and complicated shapes in magnets, we propose using cover - magnetic mechanism.
Potential hazard to health – tiny shards of magnets are risky, if swallowed, which gains importance in the context of child health protection. It is also worth noting that small elements of these magnets are able to be problematic in diagnostics medical after entering the body.
Due to complex production process, their price exceeds standard values,

Lifting parameters

Highest magnetic holding force – what contributes to it?

Holding force of 2.33 kg is a theoretical maximum value executed under specific, ideal conditions:

using a base made of mild steel, functioning as a circuit closing element
with a thickness minimum 10 mm
with an ideally smooth touching surface
with zero gap (without impurities)
during detachment in a direction perpendicular to the mounting surface
at standard ambient temperature

Lifting capacity in practice – influencing factors

Real force is influenced by specific conditions, mainly (from most important):

Air gap (betwixt the magnet and the plate), because even a tiny distance (e.g. 0.5 mm) results in a reduction in lifting capacity by up to 50% (this also applies to paint, rust or dirt).
Force direction – remember that the magnet has greatest strength perpendicularly. Under shear forces, the holding force drops drastically, often to levels of 20-30% of the nominal value.
Metal thickness – the thinner the sheet, the weaker the hold. Part of the magnetic field penetrates through instead of generating force.
Material type – ideal substrate is high-permeability steel. Hardened steels may generate lower lifting capacity.
Smoothness – full contact is possible only on smooth steel. Any scratches and bumps create air cushions, weakening the magnet.
Thermal factor – high temperature weakens magnetic field. Exceeding the limit temperature can permanently demagnetize the magnet.

Lifting capacity was assessed by applying a steel plate with a smooth surface of optimal thickness (min. 20 mm), under vertically applied force, however under shearing force the holding force is lower. Moreover, even a small distance between the magnet and the plate lowers the load capacity.

H&S for magnets

Electronic hazard

Device Safety: Neodymium magnets can ruin payment cards and sensitive devices (heart implants, hearing aids, mechanical watches).

Phone sensors

Navigation devices and mobile phones are highly sensitive to magnetic fields. Close proximity with a strong magnet can permanently damage the internal compass in your phone.

Do not drill into magnets

Mechanical processing of neodymium magnets carries a risk of fire risk. Neodymium dust oxidizes rapidly with oxygen and is difficult to extinguish.

Operating temperature

Standard neodymium magnets (grade N) lose magnetization when the temperature surpasses 80°C. The loss of strength is permanent.

Serious injuries

Big blocks can break fingers in a fraction of a second. Never put your hand between two attracting surfaces.

Keep away from children

Absolutely store magnets out of reach of children. Ingestion danger is significant, and the consequences of magnets connecting inside the body are very dangerous.

Material brittleness

Despite the nickel coating, neodymium is delicate and cannot withstand shocks. Avoid impacts, as the magnet may shatter into hazardous fragments.

Handling rules

Handle magnets consciously. Their immense force can shock even experienced users. Plan your moves and do not underestimate their power.

Skin irritation risks

Some people suffer from a sensitization to Ni, which is the common plating for NdFeB magnets. Prolonged contact may cause an allergic reaction. We suggest wear protective gloves.

Life threat

Warning for patients: Strong magnetic fields affect electronics. Keep minimum 30 cm distance or request help to work with the magnets.
